WA-Quantum GmbH's Quantum Chips

I should clarify, I'm not saying that it won't change the sound as I have not tried one and therefore have no opinion that's worth anything on the sound subject. I do think that calling it "Quantum Material" is just some marketing BS though.

yeah, the weord quantum gets thrown about in this hobby quite often. Still, there is something going on with these stickers. I have placed one of the Cable chips with Blu Tack on my main house circuit breaker. Not sure how to tell if it is doing anything however. Perhaps my electric bill will go down?

The vendors clearly use the term "quantum" in their marketing literature yet provide little or no information beyond that. Those are the only "facts" provided. So make of it what you will.

You overlooked one key bit of data provided on the manufacturer's site.

"Eight specifically programmed types available."

Make of it what you will. Heh

Let's see, what else could the WA Quantum Chip possibly be if it doesn't contain quantum material? Something that can be "programmed" for each application, something that cannot be seen (maybe it's in the ink used to make the W and A on the stickers....hmmmmm), something that apparently can improve the sound, do nothing, or hurt the sound. Can we rule out PWB Morphic Message Foils, Cream Electret and Leaf Green Cream, constrained layer damping and EMI/RFI absorbing ink/paint?
